This creature has tunneled under the lawn for so long the lawn is impassable. Mowing the lawn is like doing 8 seconds on the back of a bull at the rodeo, but a lot longer. Every day I awake to new mounds of dirt and a lot of them.
A friend suggested putting bubble gum down the hole, I said "Bazooka bubble gum?" I get it, when they read the cartoon in side you listen for them to laugh and dig them up?
I also considered gas. Hook a hose to the exhaust of my generator and stick the other end down his runway.
They also have a device called the blaster out here. It consists of a probe with a propane tank attached to it. After filling the runways with propane, it is ignited and blows them up, however the neighbor said it would blow up my whole lawn. With all of this in mind, I sunk to the level of "Water Boarding."
The results were excellent!!!
